TANK-DRAINING MECHANISM.

Speeicaton of Letters Patent.

Patented Aug. 22, 1916.

Application led August 26, 1914. Serial No. 858,664.

To all whom z' may concern Be it known that I, liLLrAM A. BOURELL,

a citizen of the United States, residing at Chicago, in Cook county, and State of Illinois, have invented certain new and useful Improvements in Tank-Draining Mechanism, of which the following is a specification.

My invention relates to tank draining mechanism and more particularly to such devices for draining ice tanks of refrigerator cars. r

One obj ect of this improvement is the provision of a device of the character mentioned for the purpose of maintaining brine or other liquids in the tanks of a refrigerator car until it is desired to empty such tanks, thereby preventing such brine or other liquids from dripping along the tracks and causing deterioration of the latter.

A further object isa provision of a special valve and operating mechanism which is locked in closed condition when the hatch and hatch plug of the refrigerator car are in operative positions.

Other objects will appear hereafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

My improvement will be best understood by referring to the accompanying drawing forming a part of this specification and in which- Figure 1 is a fragmental transverse section of a refrigerator car taken through its ice tanks and embodying my invention; Fig. 2 is a fragmental longitudinal view of the same; Fig. 3 is a section taken on line 3-3 in Fig. 1; Fig. 4 is an enlarged fragmental section showing a lever employed in the construction; Fig. 5 is an enlarged side view of a valve used in the construction; and Fig. 6 is a section taken on line 6 6 in Fig. 5.

The preferred form of construction, as

illustrated in lthe accompanying drawing,-

comprises my improvement fitted to any conventional or preferred form of refrigerator ear having a wall 7, floor 8, and roof 9. At each end of such refrigerator cars are provided ice tanks 10. The tanks 10 at each end of the car are similar in construction, hence it will only be necessary to show a p0rtion of the tanks at one end of the car. At each end of the car there may be one or more tanks reaching across such end. When there are more than one of such tanks 10 they are interconnected by a suitable connection 11 to permit communication of the liquid from one of such tanks to its next adjacent. The tanks 10 are mounted on any suitable support 12 to position them slightly above the iioor 8. In the space between the bottoms of the tank 10 and fioor 8 is a pan 18 adapted to catch any water which escapes from such tanks. The water from tank 13 is conveyed through a discharge pipe 141 extending through the bottom of the car and allowed to escape. Over the lower end of pipe la is a cup 15 adapted to form a trap, working in the usual manner, to seal the discharge opening of the drip pan 13.

The parts of the car referred to are in ordinary use. lviy invention consists in fitting to these parts a suitable valve and operating mechanism for controlling the passage of the brine, or other liquids, from the tanks 10. For this purpose I provide a novel formv of valve made up of a base 16 having a discharge opening 17 registering with a corresponding opening 18 in one of the interconnected tanks 10. The base 16 is connected to the tank 10 in any suitable manner to form a liquid-tight joint. On base 16 is provided a boss 18, which latter is provided with an annular groove 19 around the opening 17 and in the groove 19 is mounted aV yieldable valve scat 20, preferably of a rubber composition. The outer face of the seat 20 preferably extends slightly beyond the outer surface of the boss 16 so that suoli valve seat will be slightly compressed by its coperating valve when the latter is in closed condition. A part of the base around the groove extends over the peripheral edge of the valve seat holding the latter securely in the groove.

rlhe base 16, is provided with an ear 21 and a lever 22 pivoted to the car 21, as at 23. Formed on one edge of lever 22 is a valve 22 which is adapted to slide over the face of valve seat 2O and compress the latter to form a liquid tight joint. In order to insure the valve 22 forming a proper joint with its coperating valve seat 20, guides 24 are formed on base 16 and disposed slightly at an angle to the face of valve 2O so that when valve 22 moves across the valve seat 20 a wedging action will be accomplished. The valve 22 is also wedge shape, as clearly set forth in Fig. 6, to form an equal bearing over the inner surface of such valve on its seat when such valve is in closed condition.

At the top oi' the tank 10 containing diss charge opening 17 is mounted a manually operable lever 25, pivoted, as at V26, to a suitable portion of the car. The lever 25 is connected to the lever 22 by means of a connecting rod 27 to cause operation of the valve 22 upon operation oi the lever 25. The lever 25 is positioned immediately under a hatch plug 2S which seals the top of the tanks 10. The lever 25 is arranged sufficiently close to the hatch plug 2S so that it is impossible to place the hatch plug 28 in `its, operative position without first ino-ving lever 25 to its lower-most position. Such lower-most position of lever 25 causes valve 22 to be in closed position as will be readily understood from the drawing. Above the hatch plug 28 is a hatch 29 which closes a suitable openingV in the roof 9 of the car. The hatch plug 28 and hatch 29 are of conventional construction and used in all refrigerator cars.

I claim: Y

1. In combination, a base member having Van opening therethrough and an annular groove around the openingl and' extending from the face oi said base inwardly of the latter with the inner portion of the groove 2. In combination, a base member-having an opening therethrough and an annular groove around said opening; Van annular' val-ve seat securely held in said groove and extending above said base; a guide disposed at an angle to the base; and a wedge-shaped valve pivoted to the base at one side of said opening and adapted to move between Vthe guide and valve, saidangular guide pressing the valve against said seat and compressing the latter to form a fluid-tight Joint. In testimony whereof I have signedmy name to this specification, in the presence offA twol subscribing witnesses, onthis 21st day of August A. D. 1914.
